Still having the issue myself, I'm afraid. I submitted a ticket, but I can't respond to it because I can't cut and paste or attach pictures of the console code they asked for and it's too long to type out.
In addition to trying the fullscreen trick mentioned above, I uninstalled and reinstalled tequila and Homecoming, as well as adding them to the exceptions list for Windows Defender. Worked well for about 15-20 minutes, but it still stalls out finding the dbserver periodically when zoning/loading in for the first time. Sometimes it will start up fine, but the moment I hit a mission door, it can't find the dbserver.
Edit to add:
I tried the ping tests mentioned in this thread: https://forums.homecomingservers.com/index.php/topic,2027.0.html
The 40.67.254.36 IP address timed out.
